Study of the trabecular projections (Chordae Willisii) of the superior sagittal sinus.
The trabecular projections or Chordae Willisii were studied in the internal surface of the human superior sagittal sinus, being defined and quantified as to having relation with afferent veins to the sinus, as to their lateral or medial location and also in the anteroposterior direction. The results indicate a predominance of trabecular projections with no relation to afferent vessels to the sinus in its medial portion and central region, as well as predominance of these projections on the left side. The number of trabecular projections related to afferent vessels was nearly the same when left and right sides of the superior sagittal sinus were compared.
